01 The Rule
Every page below the homepage must include both visible breadcrumb navigation and BreadcrumbList JSON-LD schema. Breadcrumbs must accurately reflect the page's position in the site hierarchy.
Breadcrumb Navigation & Schema
Last updated: 2025-09-15
02 Rationale
Breadcrumbs serve dual purposes: they help users navigate and they communicate hierarchy to search engines. BreadcrumbList schema enables breadcrumb display in search results, improving CTR by showing site structure directly in the SERP.
03 Implementation
- Show visible breadcrumb trail on every page below homepage
- Include BreadcrumbList JSON-LD matching the visible breadcrumbs
- Use the canonical URL path — not the referrer path — for breadcrumbs
- Each breadcrumb item must link to a real, indexable page
- Homepage is always the first breadcrumb item
04 Common Violations & Consequences
Violation
Breadcrumb schema doesn't match visible breadcrumbs
Consequence
Schema validation errors; rich results may be suppressed
Violation
Breadcrumb links point to redirect or 404 URLs
Consequence
Broken hierarchy signal; poor user experience
Violation
No breadcrumbs on product/detail pages
Consequence
Lost SERP real estate; missed hierarchy signal
05 The Fix
Implement breadcrumbs as a template component that auto-generates from the URL path or category hierarchy. Include matching BreadcrumbList schema. Validate with Google's Rich Results Test.
